Use the information about igneous rocks A–D to classify each one as intrusive or extrusive and basaltic or granitic. Fill in the chart with A, B, C, or D. Rock A—dark-colored large grains Rock B—large crystals, high percentage of silica Rock C—fine-grained texture, light-colored Rock D—from Hawaiian volcano area, no visible crystals Extrusive Intrusive Basaltic 1. 2. Granitic 3. 4.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
